AB  - Double bond migration in N-allylindoles has been investigated as a method to access N-vinyl derivatives of this heterocycle. The optimal reaction conditions employed t-BuOK or NaH in DMSO as the solvent at room temperature to afford the products in yields ranging from 51 to 99%. Although in some cases a high degree of stereoselectivity was observed, preferential formation of either the Z- or E-isomer was not predictable. The developed methodology was employed in the synthesis of (+/-)-debromoarborescidine B.

AB  - Intramolecular Pd-catalysed cyclisation reactions for the preparation of bicyclic compounds have been studied as a model system towards the synthesis of corialstonine and corialstonidine. Significant differences in reactivity have been observed for the cyclic allyl alcohols possessing O-protected and free OH functionalities. Cyclisation via the intramolecular Heck reaction, for both derivatives, proved to be highly regioselective and while the O-protected compound favoured the exo mode of cyclisation, the unprotected alcohol preferred the endo cyclisation pathway. Brief computational studies were carried out in order to obtain further insight into these processes.

AB  - A method for the stereoselective homologation of -amino acids into syn-α-hydroxy-β-amino acids is described, based on the conversion of stereoisomeric cyanohydrins into trans-oxazolines. The synthetic potential of the method is illustrated in the enantioselective formal synthesis of Bestatin.
AB  - Opisana je metoda za stereoselektivnu sintezu α-hidroksi-β-aminokiselina syn-konfiguracije, polazeći od α-aminokiselina, kao prirodnih hiralnih prekursora. Enantioselektivnost procesa zavisi od strukture polazne aminokiseline, kao i reakcionih uslova. Primena ove metode ilustrovana je u sintezi (2S,3R)-3-amino-2-hidroksi-4-fenilbutanske kiseline, konstituenta nekoliko važnih biološki aktivnih jedinjenja.
